WCB rebate calculator. See whether COR pays for itself.
COR and SECOR certification unlock a direct WCB premium rebate in most - but not all - provinces (Saskatchewan and New Brunswick have no COR-linked rebate). For most Alberta contractors, the annual rebate covers the amortised audit cost within the first year. Enter your province, certificate type, and annual WCB premium to see the numbers.

WCB Partnerships in Injury Reduction (PIR)
PIR pays the highest of three measures, capped at 20%: 5% for simply maintaining COR (10% in your first certified year), up to 20% for improving your safety performance, or up to 20% for claim costs well below your industry average. There is no separate SECOR rate - SECOR is a COR, and earns the same structure. Registration in PIR is required and is separate from certification.
These are estimates only. WCB rebate rates and qualifying conditions vary and change. The actual rebate depends on your experience rating, your industry rate group, your certification status at fiscal year-end, and applicable WCB rules in your province. Verify current rates with your provincial WCB before making financial decisions. Audit costs are typical ranges - your actual cost depends on operation size, scope, and certifying partner.
How the WCB rebate works in Alberta.
Alberta's Partnerships in Injury Reduction (PIR) program is administered by WCB Alberta alongside the province's certifying partners - ACSA, Energy Safety Canada, and AASP. PIR pays the highest of three measures, capped at 20%: 5% for simply maintaining COR (10% in your first certified year), up to 20% for improving your safety performance, or up to 20% if your claim costs run well below your industry average for two years running. There is no separate SECOR tier - SECOR is a Certificate of Recognition and earns the identical structure. Registration in PIR is required and is separate from certification itself.
The rebate is not automatic. Your company must hold a valid COR or SECOR certificate on December 31st of the rebate year. The certifying partner submits your certification status to WCB, and WCB calculates the rebate based on your experience rating, your industry rate group, and your premiums paid during the year. Rebates are paid in the spring of the following year.
A lapsed certificate - even for a few weeks over year-end - forfeits the rebate for the entire year. For a company paying $100,000 in annual WCB premiums receiving the 5% baseline, a lapse costs about $5,000 in forfeited rebate, often far more than the cost of keeping the audit schedule current.

Questions about the WCB rebate
- How much is the Alberta WCB PIR rebate?
- PIR pays the highest of three measures, capped at 20%: 5% for simply maintaining COR (10% in your first certified year), up to 20% for improving your safety performance, or up to 20% if your claim costs run well below your industry average for two years. There is no separate SECOR rate - SECOR earns the identical structure. Most companies without a standout claims record receive around 5%, not the 20% ceiling.
- Does the COR audit cost pay for itself through the rebate?
- Often, yes. A company paying $80,000 in annual WCB premiums typically receives around $4,000 per year at the 5% baseline. Alberta certifying partners do not publish auditor fee schedules - audit cost is negotiated directly with the auditor, with market rates commonly running $3,000 to $15,000, amortised over three years at roughly $1,000 to $5,000 per year. Even the conservative 5% rebate usually covers that amortised cost at that premium level. Smaller operations with very low WCB premiums may not fully break even on audit cost alone.
- When is the Alberta PIR rebate paid?
- WCB Alberta pays PIR rebates in the spring following the rebate year. To qualify, the company must hold a valid COR or SECOR certificate at December 31st. A certificate that lapses before year-end forfeits the rebate for the full year - even if reinstated in January.
- Can I get the rebate in my first year of COR certification?
- Yes. If your initial COR certificate is issued before December 31st and remains valid at year-end, the company qualifies for a PIR rebate for that year. This is one reason companies prioritise completing their initial audit before year-end when possible.
- Do BC and Saskatchewan have similar rebates?
- Partly. BC's WorkSafeBC COR Incentive pays 10% of base assessment premiums. Saskatchewan has no equivalent - WCB Saskatchewan's experience rating program does not reference COR at all, so a Saskatchewan COR earns no direct premium rebate, only an indirect benefit through fewer claims improving your experience rating over time.
